Product details
Overview
MAX4674EEE+ from Maxim Integrated is a low-voltage CMOS quad 2:1 analog multiplexer/demultiplexer in a 16-pin QSOP package, featuring 4Ω max on-resistance at +5V, 0.4Ω max RON matching between channels, and 18ns max turn-on time. It operates from a single +1.8V to +5.5V supply and supports rail-to-rail signal handling for audio/video routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4674EEE+ datasheet, MAX4674EEE+ pinout, MAX4674EEE+ application, or MAX4674EEE+ equivalent, key selection criteria include guaranteed RON flatness (±0.8Ω), -114dB crosstalk at 1MHz, TTL/CMOS logic compatibility, and QFN/QSOP/TSSOP/SO package flexibility across voltage rails.
Technical Context
The MAX4674EEE+ implements four independent bidirectional 2:1 analog switches controlled by a single address input (A0) and active-low enable (EN). Each switch features break-before-make timing (1ns max) and internal ESD protection diodes on all analog terminals.
Its digital interface accepts TTL/CMOS logic thresholds-VIH = 2.4V and VIL = 0.8V at +5V supply-with A0 and EN tolerant up to +5.5V, enabling mixed-voltage control (e.g., +3.3V supply with +5V logic signals).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 4Ω max at +5V supply - ensures minimal signal attenuation and power loss in precision analog paths |
| RON Matching | 0.4Ω max between channels - enables accurate gain/phase matching in multi-channel signal routing |
| Turn-On Time (tON) | 18ns max - supports high-speed switching in communications and sampling applications |
| Crosstalk | -114dB at 1MHz - prevents interference between adjacent switched channels in dense layouts |
| Off-Isolation | -67dB at 1MHz - maintains signal integrity when switches are disabled in sensitive analog circuits |
| Supply Range | +1.8V to +5.5V single supply - simplifies power architecture in mixed-signal embedded systems |
| Logic Compatibility | TTL/CMOS thresholds at +5V - eliminates level-shifting requirements for standard microcontroller interfaces |
Pinout & Package
MAX4674EEE+ uses a 16-pin QSOP package (4.4mm × 5.0mm, 0.635mm pitch) with exposed pad not present in this variant. Pin functions are validated per Maxim's official pin configuration diagram and truth table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A0) | Address Input | Selects NO1/NC1 or NO2/NC2 path per switch pair; CMOS/TTL-compatible |
| 2 (NC1) | Normally Closed Terminal | Analog path closed when A0 = 0; connects to COM1 in default state |
| 3 (NO1) | Normally Open Terminal | Analog path closed when A0 = 1; connects to COM1 only during selection |
| 4 (COM1) | Common Analog Terminal | Shared I/O node for Switch 1; bidirectional signal path with rail-to-rail capability |
| 15 (EN) | Enable Input (Active Low) | Disables all four switches when high; reduces leakage and power consumption |
| 16 (V+) | Positive Supply | Single supply rail powering analog switches and logic; range +1.8V to +5.5V |
| 8 (GND) | Ground Reference | Return path for supply and analog signals; internal ESD diodes reference this node |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog inputs from GND to V+, eliminating clipping in full-scale sensor or DAC interfaces |
| Guaranteed RON flatness | ±0.8Ω over full signal range - preserves linearity in audio and instrumentation amplifiers |
| Low off-leakage current | 0.5nA max at +25°C - critical for high-impedance sensor front-ends and battery-powered systems |
| Break-before-make switching | 1ns max interval - prevents momentary short-circuits during channel transitions in relay-replacement designs |
| High-frequency isolation | -114dB crosstalk at 1MHz - enables clean multi-channel video/audio routing without external shielding |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG732BRUZ | 32-channel, 4.5Ω RON, SPI interface, +3V/+5V supply | Higher channel count but serial control adds latency and MCU overhead | Choose ADG732BRUZ only when expanding beyond 4 channels or requiring daisy-chain configuration |
| TS5A23157DGSR | Dual 2:1, 0.9Ω RON, +1.65V to +5.5V, smaller 10-pin VSSOP | Lower RON but only two switches; lacks enable pin and channel matching spec | Choose TS5A23157DGSR for space-constrained dual-switch needs where ultra-low RON outweighs quad functionality |
Compared with MAX4674EEE+, ADG732BRUZ offers scalability at the cost of real-time parallel control, while TS5A23157DGSR trades channel count and enable functionality for lower on-resistance and footprint-making MAX4674EEE+ optimal for balanced quad-switch performance in industrial and audio systems.

FAQ
What is the maximum operating supply voltage for MAX4674EEE+?
The MAX4674EEE+ supports a single-supply range of +1.8V to +5.5V. Absolute maximum rating for V+ is +6V, but sustained operation above +5.5V risks permanent damage. At +5.5V, parameters such as RON and leakage remain within datasheet limits, and the device maintains full TTL/CMOS logic compatibility when V+ = +5V.
Does MAX4674EEE+ support rail-to-rail analog signal operation?
Yes, MAX4674EEE+ supports rail-to-rail analog signal handling: input and output voltages can swing from GND to V+ without distortion or clipping. This is confirmed in the Electrical Characteristics table under "Analog Signal Range" (0V to V+), and enables direct interfacing with sensors, DACs, and ADCs operating at the supply rails.
What is the function of the EN pin on MAX4674EEE+?
The EN pin on MAX4674EEE+ is an active-low enable input that globally disables all four 2:1 switches when driven high. When EN = high, all switches enter high-impedance off-state with 0.5nA max off-leakage. This feature allows system-level power gating and prevents signal coupling during standby-critical in battery-powered and noise-sensitive applications.
Can MAX4674EEE+ be used with +3.3V logic while powered from a +5V supply?
Yes, MAX4674EEE+ supports mixed-voltage operation: A0 and EN tolerate up to +5.5V regardless of V+, so +3.3V logic signals can safely control the device even when V+ = +5V. The logic thresholds scale with supply-VIH = 2.4V and VIL = 0.8V at +5V-ensuring reliable switching without external level shifters.
Is the MAX4674EEE+ pinout compatible with other packages in the MAX4674 family?
No, the MAX4674EEE+ (16-pin QSOP) has a different pinout than the QFN variants (e.g., MAX4674EGE). While functional signals (A0, EN, COMx, NOx, NCx) are present across packages, their physical locations differ significantly-especially GND, V+, and no-connect pins. PCB layout must be package-specific; no pin-to-pin compatibility exists between QSOP and QFN versions of MAX4674EEE+.
